[EXIM] lock file

    Well I solved the problem adding ns.fii.utp.ac.pa to the
local_name variable, but I jump to another problem.

The following is the output of the msglog :

1998-04-23 13:53:00 rriley@??? <rriley@???>:
local_delivery transport deferred: no such file or directory: creating
lock file hitching post
/var/mail/rriley.lock.ns.fii.utp.ac.pa.353f8e22.0000010f

    I looked to the /var/mail discovering that there is no such
directory so I created it trying to solve the problem with no succes. 
    I suppose the answer is on the following lines which I don't
understand at all:

                This is how I have set the "configure" file

local delivery:
    driver= appendfile 
    file= var/mail/${local part}
# group = mail
# mode = 0660    

    Why Exim is trying to creat a lock file?

                                cheers,
                                           Rolando Riley
